SURFACE-WATER RECORDS

PERIOD OF RECORD - DAILY DISCHARGE--June 1903 to November 1906, April 1907 to November 1915, April 1916 to October 1919, and October 1921 to September 1924 (published as "at Broncho" or "near Broncho"), and May 1943 to current year. Monthly discharge only for some periods published in WSP 1309.
PERIOD OF RECORD.--DAILY GAGE HEIGHT--October 2000 to current year.

Previous locations and datums are as follows:

May 29, 1903 to March 23, 1905; Chain gage at site 4 miles downstream at different datum.

March 25, 1905 to September 30, 1924; Chain gage at site 3 miles upstream at different datum.

April 24 to October 27, 1943; Staff gage at present site and datum.

October 28, 1943 to May 1946; Wire weight gage at present site and datum.

From 1903 to 1924 station was published as Knife River at or near Broncho, ND.

REMARKS -

Accuracy of records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years. For water years 2014 onward, records good except for estimated discharges, which are poor, unless otherwise noted.

Peak streamflow data from 1903 to 1924 was added March 2024 after review of the available information. Due to the low accuracy of the highwater data during this timeframe, the momentary, or instantaneous, peaks were never published. The daily mean values were of acceptable uncertainty as determined in Water Supply Paper 1309. The annual peak values from water years pre 1943 were added as maximum daily mean values and were coded as such.

EXTREMES OUTSIDE PERIOD OF RECORD - Flood of March 26, 27, 1943 reached a stage of 26.7 ft, from floodmark and discharge was 11,500 ft³/s from rating extension. The 1943 flood was the highest since 1903 according to information from local resident.

EXTREMES FOR PERIOD OF RECORD - Maximum peak stage, 27.73 ft, March 22, 2009, from floodmark.

WATER-QUALITY RECORDS

PERIOD OF RECORD - Water years 1950, 1964-65, 1972 to 2012.
